Cast Iron Hand Lapping Plates

Hand Lapping Plates are suitable for laboratory, toolroom or maintenance workshops and can be used for lapping parts to extreme flatness in low volumes.

These plates are made from high quality, low porosity grey cast iron (Grade 300 to BS1452) and are usually serrated with a square cross-hatched pattern. Solid (unserrated) hand lapping plates are available for use with very small workpieces.

These are used with an abrasive grit, applied in paste form to give a uniform dull matt finish on a wide variety of metallic and non-metallic materials. Three standard sizes of plate are available (Other sizes available upon request):
